Used GATAN 691 #9253807 for sale

GATAN 691 is a "ion milling" equipment, a type of physical etching used in the fabrication and inspection of nanoscale samples, such as semiconductor devices. The system is comprised of an ion source, power supply, vacuum chamber, various beam concentrators, and digital automation software. The unit is capable of precision performance down to 0.1 nanometres accuracy. It is capable of etching down to a depth of 150 nanometres and is one of the most accurate and reliable ion milling systems available. 691 is constructed from durable stainless steel and other rust-resistant materials, designed to ensure long-term reliable operation. The basic components of the machine are the two ion sources, a cesium and a krypton. Cesium is the primary source, with its large current and energy density resulting in faster etching. The tool's low particle neutralizer also allows higher etch rate performance. The krypton source is used for higher energy milling and imaging applications. Both sources are housed in a vacuum chamber with an elaborate cooling asset and various beam concentrators. The design ensures reliable operation and maximum performance. GATAN 691 is powered by a 400 Watt DC power supply and is controlled via digital automation and software. An automated control panel is included to program and monitor the model's performance, with the equipment capable of analyzing multi-masked wafers and samples. A wide array of imaging and analytical routines can also be performed by the system. These include X-ray spectroscopy, X-ray beam surface mapping, mechanical analysis, optical mini-integrated reflectance spectroscopy, and others. This wide range of analytical tools makes it the ideal choice for quality assurance in the fabrication of nanoscale devices. Finally, safety features are built in to provide protection against any potential hazards associated with ion milling. This includes an autostop safety unit that automatically shuts off the power supply in the event of an emergency. Other onboard safety systems measure and maintain the machine's vacuum pressure as well as preventing accidental errant ion beams. In summary, 691 is one of the most reliable and precise ion milling systems available. It is capable of etching nanoscale samples with tremendous accuracy and offers a wide array of analytical and imaging routines to ensure quality assurance in the production of nanoscale devices. Its multitude of safety features also ensures the highest levels of protection to both the user and the tool itself.
